The AJH Synth Ring SM is three modules in one: a ring modulator based on an analog transistor core design, a sub bass generator that creates tones 1 and 2 octaves down, and a 5 input mixer based on the classic Moog CP-3 design. This mixer is used to combine the original inputs, ring modular, and sub bass sounds; you can override them by patching in alternate inputs. The bonus preview movie from the soon-to-be-released Eurorack Expansion course focuses on the ring modulator section, showing a few different applications as well as really focusing on the waveforms and harmonic spectra it creates so that you better understand how a ring modulator works:

The Verbos Complex Oscillator is an interesting interpretation of the classic Buchla “complex oscillator” pair where one modulates the other. It too has two oscillators with internal wiring and options so the modulation oscillator on the left can amplitude or...

A nice option for an analog VCO to add to your system is the Intellijel Dixie II+: it’s small, has excellent tracking, supports linear and exponential FM as well as PWM and hard sync, and has six different waveforms. In this movie, I demonstrate creating a hard sync patch with the Dixie II+. For those who wonder exactly what’s going on when you use sync, I focus heavily on what’s happening with the waveform output. I also look at the Dixie II+’s unique Flip function.

Most know the Moog Mother-32 as being a neat little semi-modular synthesizer. However, it also contains a step sequencer with lots of nice options. While you’re paused on a note during the creation of a sequence or while editing it after the fact, you can also edit duration, glide, ratcheting (repeats), accents, and rests for that step. In this post, I’ll go over how to access those options and show you how to program ratchets and glides.

A lot of people have bought Moog Mother-32 semi-modular synths as their entry point to modular synthesis. Therefore, I’m creating a couple of courses based on using the Mother-32 in this environment. Here are two videos excerpted from the first course which will get a Mother-32 owner up and running, including installing it in a Eurorack case.
